what is the y-intercept of y=2(x+3)(x-4) it is-24 but why dont you multiply 2*-4
+93 You are not suppsed to multiply out this problem, this looks like a quadratic intercept form.
quadratic intercept form: y=a(x-p)(x-q)
a = vertical shift/stretch
p = root/x-intercept
q = root/other x-int
+37146 when this eqaution intercepts the y-axis ....the 'x' value is = 0
put x = 0 in to the equation
y-intercept = 2(0+3)(0-4) = -24
